This video shows High Level Throwing Patterns in which the arm starts down by the side, the stride is initiated, the trunk turns back against the hips and the hips open up towards ball release. With this proper arm pattern and hip to trunk relationship, the body now has the ABILITY to create resistance in a throw. This is shown using the water bottle. As the water shifts in the bottle, it allows an athlete to feel the resistance created by the body.

As the lead leg is about to land, the arm is moving through its pattern and moving through external rotation towards ball release. The elbow must unhinge or extend near the head or body without drifting forward. When this happens, the proper timing of pronation can occur through ball release.
